COMBINED LooK AND LATCH.

SPECIFICAION ferrning part of 'Letters Patent No. 692,068, dated January 28, 1902.

i Application led .Tune 4:, 1901.

T all whom, t may concern:

Be it known that I, MARCUS C. PATRICK, a citizen of the United States,`residing at Seattle, in the county of King and Stateof Washington, have inventednew and useful Improvements in a Combined Lock and Latch,4 of which the following is a specification. p

This invention relates to a combined lock and latch, and in some respects it is in the` nature of an improvement upon the device covered by Letters Patent No. 657,385, granted to me September 11,1900; and the present as Well as the prior invention shows a combined lock and latch wherein certain of the parts are housed Withinthe knobs and are adapted to lock said knobs against rotation; but it will be apparent that certain of the. features of the invention are capable of advantageous incorporation in latches or locks of other kinds.

The latch and lock has improved means for locking and releasing the knobs and for also deadlocking the bolt, so that the latter cannot be actuated by the knobs either with or Without akey. l

The invention also involves several other advantageous features, which, with theforegoing, will be set forth at length hereinafter, While the novelty will form vthe basis of the appendedmlaims. e

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part ofA this specification, and in Which- Figure 1 isa horizontal central section of a combined lock and latch including my irnprovernents. Fig. 2 is a face View of the bolt-` casing and parts therein, showing also the knob-spindle and a bolt-actuating spindle in cross-section, together with the deadlocking and operating device on the latter. Fig. 3 is a detail of thebolt-actuating spindle and the parts carried thereby. Fig. 4 is a detail of a yoke. Fig. `5 is an inside face View of the inner escutcheon-plate,showin g more especially the means for controlling the position ofthe bolt-actuating spindle; detail views.

Serial No. 63,152. (No model.)

aredsposed and operate in the manner set forth in my prior Letters Patent hereinbefore alluded to, and therefore I shall brie y describe the same.

Referring now to the drawings, the casing for the bolt is denoted by l0, and it houses the sliding bolt l2, the latter being adapted tobe shot into a suitable keeper (not shown) to fasten the door carrying the said bolt or latch casing.

`The upper and lower Walls of the latch-casing have inwardly-disposed vertically-aliued" osets, as 10', while the head ofthe bolt or latch has a transverse shoulder 12', which coiled pressure-springs, as 13, are adapted tobear, the opposite ends ot' said springs engaging the offsets l0', and said springs serve to normally shoot the bolt out- The bolt is furnished with rearwardly-extendingvparallel legs, as 14C, having shoulders, as'le', wat their outer ends adapted to beengaged by the oppositely-disposed lugs 15 on the boss 15, loi cated inside the casing 10 and havinga square central aperture to receive the knob-spindle 16, which extends through said casing. By turning said knob-spindle in either direction the boss 15 can be rotated so as to 'carry one of` the lugs l5.' against one of` the shoulders 14 at the inner end of the bolt l2 for the purpose of retracting the same.

The escutcheon-plates are denoted by 2O and 22, and they are mounted upon opposite sides of the doorand are adjustably connected substantially in the manner shown in the hereiubefore-mentioned patent.

The inner knob is denoted by 18, its shank extending into the central offset hub or boss 19 of the inner escntcheon-plate and being adapted to receive the inner squared end of the The stem of the knob 18 is encircled by the Washer 20, countersunk in the inside face of the inner escutcheon-plate, and the Washer is held in place by means of a spring-clamp 2l, lying in an annual groove near the inner end of the shank of the inner knob 18. By turning said inner knob the spindle 16 can be rotated so as to draw back the bolt 12.

. The outer escutcheon-plate is designated by 22, and it has substantially centrally thereof the inwardly-disposed annular flange 23,

IOS

which fits against the cap or disk 24, the latter having a key, as 24', to enter a slot or notch in said annular iiange to prevent the disk or cap from turning.

The spindle 16 is rigid with the outer knob 25, and it turns in the projecting central hub 26 of the outer escutcheon-plate. The knob 25 is held in place bya Washer 25', surrounding the spindle 16, and fastened thereto by a pin 16', said Washer being also countersunk in the disk or cap 24. The spindle 16 carries near the outer knob in a transverse bore therein the slidable locking-pin 27, which is normally forced into the seat28 in the cap 24 by the spring-actuated button 29, the spring 30 of which is seated in a groove or channel in said cap opposite` to the seat 28. Normally the spring 30 through the button 29 forces the opposite end of the pin v27 into the opening 28, so that the outer knob cannot be turned. When-.the pin 27, however, is forced out of the opening or seat 28, the knob 25 can be turned so as to actuate the sliding bolt 12. The pin 27 has an annular groove to receive an eccentric-pin 31 at the inner end of the rod 32, rotative inside the outer knob and key-operated in the manner indicated in my prior patent. IVhen the proper key is inserted in the knob 25, the rod will be turned so as to carry the pin 27 out of its seat 28, whereby the said knob can be freely turned to operate through the intervening parts the bolt 12. The operation of the pin places the spring 30 under compression, so that the latter when the key is withdrawn can return the pin 27 to its primary position.

rI he bolt 12 has an elongated slot, and the spindle or bar 34 extends through the same, and its inner end passes through a perforation in the inner escutcheon-plate 20, and the hub of a thumb-piece embraces said projecting end. The said hub bears against a square shoulder 36 inside the inner escutcheon-plate, fast on the spindle 34, and said hub is held in place by a screw entering said projecting end of the spindle. The spindlescarries at its outer end a cam or eccentric 37, having a sleeve portion 37 snugly fitted onto the spindle, whereby the cam and spindle are adjust- .ably connected to adapt them to doors of different thicknesses. This cam is adapted to engage the yoke-shaped end 38 of the slide 39, projecting through a slot in the annular wall or ange 23 and guided by the cap or disk 24. The inner end of the slide 39 is contiguous to the outerend of the locking-pin 27. When the spindle 34 is rotated in the proper direction by the thumb-piece 35, the cam 37 is caused to engage the outer rounded face of the yokeshaped slide, so as to force the same, and hence the pin 27, inward, and when the pin is out of the seat 28 the said spindle can be thus held, whereby the knob 25 can be freely turned to rotate the'spindle 16 for the purpose of drawing back the bolt 12. The said spindle may be thus held bya spring of curved form fastened suitably inside the inner escutcheon-plate 2O and the free end of which is adapted to enter grooves, as 4l, in the square faces of the shoulder 36.

The spindle 34 is square in cross-section and is embraced by the boss 42, having a substantially radial arm 43, said boss being located inside the latch-casing 10. The bolt has on its forward end a transverse shoulder 44, and back of the same the separated shoulders 45., and the radial arm 43 on the boss plays between these shoulders. Vhen the spindle 34 is operated so as to force the arm 43 of the boss 42 into a position parallel with the bolt and in contact with the shoulder 44 on said bolt, the latter will be deadlocked and cannot b e operated by the knob-spindle 16, and this relation can be maintained, of course, by the spring 40, which secu rely holds the spindle 34. When the latter, however, is rotated by hand and when the perpendicular position of the arm 43 is reached, the bolt will be released from its dead-lock position, and by continuing the motion said arm can be forced against a shoulder 45 to draw the bolt backward, even while the knob 25 is locked. When the spindle 34 is rotated in a direction opposite that followed in opening bolt 12, it operates the cani 37 in such manner as to force the yoke-shaped slide 39 backward to release the locking-pin 27. When the spindle 34- is turned to put the arm 43 down, but perpendicular, the knobs can be turned from either side during the day. By putting said arm parallel with the bolt the latter will be deadlocked, or by putting said arm in its upper perpendicular position the lock can be operated froma key on the outside.

The inner end of the slide 39, both ends of the locking-pin 27, and the working end of the button 29 are of ball form, s'o that knobs can turn easily without catching when. unlocked.

Many changes may be made wit-hin the scope of the appended claims.
